Variable refresh rate (VRR) refers to a dynamic display that can continuously and seamlessly change its refresh rate without user input. A display supporting a variable refresh rate usually supports a specific range of refresh rates (e.g. 30 Hertz through 144 Hertz). This is called the VRR range. The refresh rate can continuously vary ...
Flicker fusion threshold. The flicker fusion threshold, also known as critical flicker frequency or flicker fusion rate, is the frequency at which a flickering light appears steady to the average human observer. It is a concept studied in vision science, more specifically in the psychophysics of visual perception.
The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every ...
On 17 May 2022, members of the United States House Intelligence Subcommittee on Counterterrorism, Counterintelligence and Counterproliferation held congressional hearings with top military officials to discuss military reports of unexplained aerial phenomena (UAPs). [1] It was the first public congressional hearing into UFO sightings in the US ...
The exact refresh rate necessary to prevent the perception of flicker varies greatly based on the viewing environment. In a completely dark room, a sufficiently dim display can run as low as 30 Hz without visible flicker. [citation needed] At normal room and TV brightness this same display rate would produce flicker so severe as to be unwatchable.
The Pentagon UFO videos are selected visual recordings of Forward-looking infrared (FLIR) targeting from United States Navy fighter jets based aboard aircraft carriers USS Nimitz and USS Theodore Roosevelt in 2004, 2014 and 2015, with additional footage taken by other Navy personnel in 2019.
The Labor Day 1969 UFO Incident allegedly occurred on the night of September 1, 1969, in Berkshire County, Massachusetts when over 250 people allegedly reported witnessing a UFO, according to UFO Park enthusiasts. [1] The incident has been deemed a "significantly historic and true event" by the Great Barrington Historical Society and ...
Unidentified flying object. An unidentified flying object (UFO), or unidentified anomalous phenomenon (UAP) [a], is any perceived airborne, submerged or transmedium phenomenon that cannot be immediately identified or explained. [2] Upon investigation, most UFOs are identified as known objects or atmospheric phenomena, while a small number ...
